Pipe hanger and pipe hanger assembly

Abstract

A pipe hanger assembly is assembled from a hanger rod, a hanger block, a pipe support, at least an additional pipe support, pintles in the form of either pintle pins or bolts, and pintle retainers such as clips or nuts. The pipe supports are formed to form a throat into which a pipe is passed to engage the pipe support and the pipe support mated with the hanger block or another pipe support having an extension below the pipe support surface. The hanger block and pipe support are connected by a pintle, and lower supported pipe supports are similarly mated with the higher pipe support extension thereby forming a hanging assembly. A hanger member in the form of a “U-shaped” member also can be mated with the extension of a higher pipe support in order to suspend an additional hanger rod, hanger block and connected pipe support providing a spacing between adjacent pipe supports greater than that of two directly interconnected pipe supports.

What is claimed is:  
     
         1 . A pipe hanger assembly for supporting pipes from an overhead structure comprising: 
 a first threaded rod member;    a hanger member, said hanger member having a first hole to accept said first threaded member and at least a second hole orthogonal to said first hole, said at least second hole extending therethrough;    a first pipe support member formed as a clevis, having a pair of legs, said first pipe support member formed with an interior surface adapted to receive a pipe;    said first pipe support member further comprising a member extending from said exterior of said first pipe support member, said extending member having a hole transverse to said extending member and extending therethrough;    said pipe support member defining a hole extending transversely through each of said legs of said clevis and parallel to said hole transverse to said extending member, each of said holes through said legs aligned to accept a pintle inserted therein, and    said pintle inserted into said holes of said pipe support member and said hole transverse said hanger member,    whereby said first pipe support member is suspended from said hanger member by said pintle and said hanger member is supported by threaded engagement with said first threaded rod.    
     
     
         2 . The pipe hanger assembly of  claim 1  further comprising a second pipe support member disposed with said legs thereof and said holes transverse said legs thereof aligned with said hole transverse to said extending member and a further said pintle extending therethrough.  
     
     
         3 . The pipe hanger assembly of  claim 1  further comprising a second hanger member comprising a “U-shaped” member comprising a base portion and a pair of legs, each of said legs forming a hole through each said leg and said holes aligned with each other and aligned with said transverse hole through said extending member of said first pipe support member and a further pintle extending through said aligned holes, said “U-shaped” member further comprising a threaded hole formed in said base portion and a threaded rod engaged in said threaded hole.  
     
     
         4 . The pipe hanger assembly of  claim 3  wherein said threaded rod additionally supports a further hanger member, a further pipe support member and a further pintle.  
     
     
         5 . The pipe hanger assembly of  claim 1  wherein said pintle comprises a shaft, an enlarged head on a proximal end, and a hole transverse to shaft proximate a distal end of said shaft, and a retainer engaged in said hole transverse to said shaft.  
     
     
         6 . The pipe hanger assembly of  claim 1  wherein said pintle comprises a bolt and said bolt is threadedly engaged with a threaded retainer member.  
     
     
         7 . The pipe hanger assembly of  claim 1  wherein said hanger member comprises a block of cast material.  
     
     
         8 . The pipe hanger assembly of  claim 1  wherein said hanger member comprises formed sheet of material having at least a pair of legs and a bridging portion intermediate said legs, said legs forming holes therethrough, said legs disposed substantially parallel and separated by a distance to permit each of said holes in said legs to be disposed juxtaposed with one end of said hole extending through each of said legs of said clevis or said extended portion of said pipe support member.  
     
     
         9 . The pipe hanger assembly of  claim 8  wherein said hanger member legs are disposed exterior to said legs of said clevis.  
     
     
         10 . The pipe hanger assembly of  claim 8  wherein said hanger member legs are disposed interior to said legs of said clevis.  
     
     
         11 . A pipe support for incorporation into a pipe hanger assembly comprising: 
 a generally “U-shaped” body with a pair of legs disposed in parallel and connected to a spanning portion, said legs and said spanning portion forming an interior passage sized to accept a pipe therethrough;    said legs forming a throat, said throat having a predetermined width;    said spanning portion further comprising an outwardly extending portion of said “U-shape” and having a predetermined width dimension smaller than said throat dimension;    said legs of said “U-shaped” body defining a hole through each of said legs and said extending portion defining at least a hole, said holes in said legs and said hole in said extending portion disposed parallel and transverse to said clevis and alignable with the holes of a similar clevis identical in all respects except the size of said interior passage,    whereby said clevis may be positioned below and connected to said similar clevis by a pintle, thereby depending said clevis below another clevis for supporting a pipe positioned in said interior passage.    
     
     
         12 . The pipe support of  claim 11  further comprising a hole disposed co-axial with said pipe support and extending at least partially through said extended portion of said pipe support.  
     
     
         13 . The pipe support of  claim 12  wherein said co-axial hole is internally threaded.  
     
     
         14 . A suspension member for suspending a threaded member from a pipe hanger assembly comprising: 
 a channel member having a “U-shaped” cross-section, said “U-shaped” cross-section formed by a pair of legs disposed projecting from an intermediate bridging portion;    each of said legs having a hole extending therethrough, said holes axially aligned to each other;    a hole formed in said bridging portion and disposed orthogonally to said axially aligned holes,    whereby said suspension member may be attached to a pipe support having a portion extending therefrom and a transverse hole extending through said portion, and a pintle may be inserted into said holes in said legs and an aligned hole in an extended portion of a pipe support, and a further rod may be engaged with said bridging portion and retained therein to support a depending device.    
     
     
         15 . The suspension member of  claim 14  wherein said suspension member comprises a sheet of material formed to create said “U-shaped” cross-section and having a dimension between said aligned axis of said holes in said legs and said bridging portion and such that space intermediate an extended portion of a pipe support from which said suspension member may be suspended and said bridging portion is sufficient to provide for a nut threadedly engaged with said rod disposed intermediate said bridging portion and said extended portion of said pipe support.  
     
     
         16 . The suspension member of  claim 15  wherein said suspension member is formed with said legs having a capability of manual deflection permitting deformation of said pair of legs toward each other to permit insertion of said pair of legs within a throat of a pipe support and a deformation of said pair of legs away from each other to permit insertion of an extended portion of a pipe support therebetween.
